The beta-adrenoceptor antagonist (-)-3-({sup 125}I)iodocyanopindolol (({sup 125}I)ICYP) binds with high affinity and in saturable way to membranes of guinea pig alveolar macrophages. The equilibrium dissociation constant for ({sup 125}I)ICYP is 24.3 +/- 1.2 pM, and the number of binding sites is 166.3 +/- 13.7 fmol/mg protein (N = 4, +/- SEM). Displacement studies with selective antagonists showed that ({sup 125}I)ICYP labels beta 2-adrenoceptors on guinea pig alveolar macrophages.
